Abstract
Thirty-one members of the genus Marichromatium were analysed based on multilocus sequence analysis (MLSA) of four concatenated protein-coding genes (fusA, pufM, dnaK, recA) along with the internal transcribed spacer (ITS; 16S-23S rRNA) region and 16S rRNA gene. The restriction patterns obtained from the in silico analysis of the concatenated sequences were good barcodes for the identification of Marichromatium spp. Distinct phenotypic, chemotaxonomic and molecular differences allowed the separation of Marichromatium fluminis JA418T into a new genus in the family Chromatiaceae, for which we propose the name Phaeochromatium fluminis gen. nov. comb. nov. © 2012 Elsevier GmbH.
